I’m going to propose another theory
Beauty and the Beast and Cupid and Psyche are very similar stories. When reading a retelling of Beauty and the Beast it’s almost difficult to see where the Belle ends and the Psyche begins.
I find that the difference is in the central theme of change:
while both require one of the characters in the couple to change and grow the Beauty is perfect as is, gentle nice and all around a perfect gal, meaning that the Beast is the one who has to change and become elevated through her love.
On the other hand, Cupid is a god and while he is a huge piece of shit the narrative of the story regards him as the one holding the knowledge required for Psyche to grow up and change from a girl to a woman. He is the love that elevates the spirit incarnated.
